Order online for $79, walk into any of 2,000+ locations for a blood draw — no doctor's visit needed. Seven liver markers plus a FIB-4 fibrosis score — with results in a day, and no fasting or special preparation.
The short version
$79, one walk-in visit, results in a day
The Liver Health Test ($79) measures the enzymes and proteins that describe how your liver is working — ALT, AST, alkaline phosphatase, bilirubin, albumin, and total protein — plus a platelet count, and combines four of those numbers with your age into a FIB-4 score that screens for liver fibrosis. Order online, walk in for the draw, results in a day. Its honest limit is printed on the page itself: it screens for risk, it does not diagnose liver disease.

What the 7 markers cover — and how the FIB-4 score works
The panel reads as two groups plus a calculation. Enzymes: ALT (alanine aminotransferase, found mostly in liver cells), AST (aspartate aminotransferase, found in cells throughout the body but primarily in the liver), and alkaline phosphatase (found in liver cells and other tissue) — when liver cells are damaged or inflamed, these enzymes leak into the blood at higher levels. Proteins and waste: albumin (the main protein circulating in the blood, made by the liver), total protein (albumin plus the rest), and bilirubin (a waste product from breaking down red blood cells, which the liver clears). Platelets: the blood cells that form clots — a low count can accompany advancing liver disease. The FIB-4 score is not a measurement but a calculation from four inputs — your age, platelet count, AST, and ALT — that estimates the likelihood of advanced fibrosis. The product page gives the bands plainly: 0 to 1.29 is low risk, 1.30 to 2.67 is indeterminate or moderate risk, and above 2.67 is high risk for advanced fibrosis.
Who the test is for — the risk factors that matter
Fatty liver disease linked to metabolic health is common and usually silent: according to researchers cited on the product page, 1 in 4 people are affected, and symptoms often do not appear until disease has progressed. The test is aimed at people with risk factors — obesity, prediabetes, type 2 diabetes, or two or more features of metabolic syndrome (high blood glucose, low HDL cholesterol, excess fat around the waist, high triglycerides, high blood pressure), evidence of fatty liver on an imaging study, or ALT or AST levels that have stayed elevated for more than six months. Three guideline bodies — the American College of Gastroenterology, the American Association of Clinical Endocrinology, and the American Diabetes Association — recommend the FIB-4 calculation as a simple, accurate, noninvasive initial screening test for people with those risk factors. If none of those apply to you, this is a low-yield purchase: a normal liver panel in a low-risk person rarely changes anything.
Reading the score — and its honest limits
A FIB-4 in the low band is reassuring but not a clean bill of health — it estimates fibrosis risk, it does not rule out liver disease. An indeterminate score is the most common awkward outcome: it means follow up with your clinician, who may recommend imaging or repeat testing rather than a verdict. A high score means a higher risk of advanced fibrosis and of liver-related complications, and the same follow-up applies with more urgency. Two limits deserve stating plainly. First, the score was developed and validated in people aged 35 to 65, and because age is part of the calculation, people over 65 face a higher risk of false-positive results. Second, the score is a screen, not a diagnosis — it cannot confirm fatty liver disease or fibrosis, and it is not intended for people whose liver concerns are likely caused by viral hepatitis, alcohol-related disease, medication injury, or other specific causes. The product page suggests repeating the test every 1 to 3 years to watch the trend, or as your provider recommends.
What an abnormal marker means
Each marker points in a different direction, and the product page spells out the usual readings. High bilirubin may be a sign of liver or gallbladder disease, or of excessive breakdown of red blood cells; low levels can follow certain medications. High ALT or AST could be a sign of liver damage or liver inflammation, among other conditions. High alkaline phosphatase has various potential causes and may be a sign of liver, gallbladder, or bone disease. Low albumin may be a sign of malnutrition, infection, or liver, thyroid, or kidney disease; high albumin can simply reflect dehydration. Low platelets can lead to bleeding risk and may be due to liver disease, infections, certain medications, or bone marrow disorders; high platelets may be caused by inflammation, anemia, or a bone marrow disorder. None of these numbers diagnoses anything on its own — they are prompts for a clinician to read together, against the FIB-4 score and your history.
Eight measurements means eight chances for a borderline result, and a single slightly-out-of-range number in an otherwise normal panel is usually noise, a recent illness, a medication effect, or lab variation. Repeat testing and clinical context turn a number into a plan — a shopping cart does not.
How walk-in liver testing works
You order the test online, then visit a patient service center for a standard venous blood draw — no doctor’s order, no appointment, and no insurance needed. No special preparation is required for this test — no fasting, no timing window. Results typically post to a secure portal 1 day after your sample arrives at the lab. HSA/FSA accepted. The test must be taken by the purchaser, and it is available to adults 18 to 100. If the FIB-4 comes back indeterminate or high, the usual next step is a clinician conversation and possibly imaging — not a supplement order.

Common questions
Do I need to fast before a liver health test?
No. No special preparation is needed for this test — order online and walk in for the draw. If you take other tests in the same visit, check their prep rules separately, since some do require fasting.
What is a FIB-4 score?
A calculated score that estimates the likelihood of advanced liver fibrosis, built from four inputs: your age, your platelet count, and your AST and ALT levels. It is not a lab measurement itself — it is arithmetic on measurements the panel already takes. The product page gives three bands: 0 to 1.29 is low risk, 1.30 to 2.67 is indeterminate or moderate risk, and above 2.67 is high risk for advanced fibrosis.
What does a high FIB-4 score mean?
A score above 2.67 indicates a high risk for advanced fibrosis and for developing other liver-related complications. It is not a diagnosis — you should follow up with your healthcare provider, who may recommend additional tests such as imaging for further assessment. The same follow-up applies to an indeterminate score, with less urgency.
How often should I take this test?
Because liver fibrosis often occurs and progresses in unpredictable ways, the product page suggests repeating this test every 1 to 3 years, or as needed based on your provider’s recommendations, to monitor your liver health over time.
Can this test diagnose fatty liver disease?
No. The test screens for evidence of liver inflammation or indicators of liver disease or fibrosis — it is not intended to diagnose any form of liver disease. Diagnosis needs imaging, further testing, and a clinician reading the results against your history.
What is the difference between this test and NASHnext?
Both estimate fibrosis risk, but from different inputs. This test uses routine liver markers plus your age in the FIB-4 calculation, with results in a day. NASHnext uses four different blood markers combined by the NIS4 algorithm and takes longer for results. The liver test is the first screen; NASHnext is the more advanced step when the first screen is indeterminate or high, or when the risk is already known to be higher.
Is this a home test kit?
No. This is an in-person blood draw at a patient service center — you order online, then walk in for the sample collection. Your results arrive through a secure online portal, typically 1 day after your sample reaches the lab.
